For reference, there are 8 different eras in baseball history: the Dead Ball Era (1901-1919), the Live Ball Era (1920-1941), the Integration Era (1942-1960), the Expansion Era (1961-1976),
the Free Agency Era (1977-1993) and the Long Ball/Steroid Era (1994-2005), and the Post Steroid Era (2006-today). When searching for a player, take note of when their debut date and final
game date were, which can be found on the home page search table.
